I think you will find it is far more a matter of age and investment (or lack 
there of) in infrastructure. Parts of Tucson are great and rarely have 
issues... other parts far less so.

In particular, southern-midtown and south of downtown is horrible for power 
quality/reliability. The area is roughly bordered by Alvernon/22nd on the NE 
and Ajo/6th on the SW. Once they get stuff up and balanced it is *OK*... but 
you can expect power to go down in virtually every major monsoon storm (just 
ask me about it, Ive put a dozen hours on our datacenter generator and burned 
a 100 gallons of diesel in just this last season).

The NW side also frequently has problems, from about Ina to Marana, the Tucson 
Mountains to Thornydale. Power blips, ranging from a few missed cycles to 
5-10min outages are very common on completely clear days with no apparent 
cause.
